kApplication led April 2 tially on the line 21-2 of AFigure 1, and

, Figure 3 is a detail front elevation of the hot box. y f

Figurefi is a detail sectional view of the. oil line. Y i i Figure 5 a detail section through the tray pan.

Referring to the drawing in detail, it will be seen that the numeral 5 denotes'aconventional steam cleaner to which myimproved fire box 6 is attached by flanges -7. The front wall of this tire box is provided with an opening overV which is a pivoted closure 8. -The top of the fire box isl provided with an opening 9. An inverted V-shaped bracket 1() rises from the top across the opening 6 and has/a clamp 11 at its apex. The numeral 12 denotes an oil tank from which extends the fuel pipe 14e through a heating drum 15 of the steam cleaner 5 downwardly through the bearing 14 in the clamp 11. Y

A valve 16 is incorporated in the pipe 14. A shaft 17 is mounted in the box 6 to rise up# wardly and centrally through the opening 9,

and terminates in the lower extremity of the bearing 14;. Within .the box there is jour- ConsiderableV trouble has ben experienced 'with steam cleaners on account of not having enough heat to carry the amount of steamre quired for cleaning purposes which is usually about fifty pounds. y

Any kind of fuel may be utilized and T have had considerable success with reclaiming heavy oil. This burner may be used on any wood or coal stove7 To operate the burner a piece of waste paper or rag with some oil onit is set on fire and vdropped into .the kbox 6', through the opening in the front ywall thereof bv swinging'the vclosure 8 out of the way. The closure is put back to, place and a small amount of oil is adapted tor flow through the pipe by openingthe valve 16.

is then released and more oil is turned konv .which will increase as the heat increases, the

speed of the fan also increasing which forms This oil flows through the pipe 14 down the fanshaft vto the -fan and there combustion takes place.

The oil from the pipe 14 passes into the bearing 14: and

then flows down the outside of the shaft 17 onto the fan blades,whioh cause'the oil tok be vsprayed out centrifugally; When the fire is started in the box, a draft is created to rise through the opening 9and thereby causing the fan to turn andthe oil flows down thev Varrangement'of parts may be resorted to,

without departing from thefspirit or scope of the invention or sacrificing any of rits advantages.' i l Having thus described -my invention, what I claim as new is:

1L A-hot box oil burner comprising a loox with an opening in the top thereof, an opening in one sidewall thereof, a closure for the opening in the side wall, ay shaftextending into the box land having a fan thereonV within thebox, and avfuel line leading to the shaft,

"To v y said shaft being journaled in the fuel line and a bracket rising fromk the box andholding the 2. In combination with a lsteam cleaner, a

l fire box fixed tothe lower portionthereof and having an opening in one side wall, a closure i associatedtherewith, and anopeningin the top thereof, a bracket rising from the top of the 'tire box, a fuel line. supported in the bracket, a shaft journaled in the lowerend of the fuel line and extending through the opening in the top of the box, a spray fan' on the lower end-of the shaft within'the box, and a fuel line tank to which the line is attached.

In testimony whereof I aiix my signature.
